Title: Manufacture of sintered rare-earth permanent magnet
Inventor: TAKAHASHI WATARU
IPC: H01F41/02
Filed: 1995-06-26
Abstract: PURPOSE: To improve the dimensional accuracy and productivity of a molded body by reducing the amounts of residual oxygen and residual carbon in a sintered body by suppressing the reaction between alloy powder and a binder and, at the same time, improving the fluidity, orientational property, and lubricity of powder at the time of molding the powder. CONSTITUTION: The fluidity of slurry obtained by adding an extremely small amount of binder composed of a water-soluble polymer and water to alloy powder, such as R-Fe-B alloy power, R-Co alloy powder, etc., containing rare-earth elements and kneading the powder is improved by granulating the slurry into grains by means of a spray drier device and the orientational property of the grains in a magnetic field is improved by mixing a fatty acid ester or boric acid ester lubricant in the grains. Then, after a molding tool is filled with the grains, the grains are molded while a pulse magnetic field is impressed upon the grains.  Therefore, a sintered rare- earth permanent magnet having a thin or complicated shape and an excellent magnetic characteristic can be obtained, because the grains are disintegrated and, at the same time, the orientational property of the grains is improved and the weight fluctuation and density fluctuation of the molded body are reduced by performing the molding, sintering, and heat treatment.

Title: Automatic fuel oil feed device for filling tank
Inventor: SAKAI JUNICHI
IPC: B67D7/32
Filed: 1992-07-10
Abstract: PURPOSE:To rapidly feed fuel oil to a tank until it is filled with fuel oil without causing the liquid or bubbles of fuel oil to overflow by a method wherein, when the outlet quantity of fuel oil is restricted by detecting a fixed quantity of fuel oil fed after starting the first fuel oil feed or by detecting the liquid or bubbles of fuel oil within a period of fuel oil feed time, fuel oil feed after such a detection is returned to a large flow rate. CONSTITUTION:In an automatic fuel oil feed device 1 for filling a tank, when a liquid level sensor S1 disposed in the vicinity of a fuel oil feeding nozzle 10 detects the liquid or bubbles of fuel oil, a tank filling decision circuit 26 closes a flow rate control valve V1 through a valve control circuit 24 and stops a motor 23 by a predetermined period of time through a motor control circuit 21. Further, the tank filling decision circuit 26 decides whether a flow rate reaches a quantity of fuel oil to be fed, which is set by a setting means 27, after receiving the first input signal from a flow rate pulse oscillator 17 related to a flow rate meter 6. If it does not reach the set quantity, the motor 33 is driven to operate a pump 3, and the fuel oil is fed at a small flow rate through a bypass pipe passage 16. Furthermore, when a predetermined period of time elapses after the motor 23 is driven again, the flow rate control valve V1 is opened to shift to a large flow rate.

Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To shorten the time until when much electric power can be taken out and to lighten the load of calculation of output electric power, etc., by allowing an inverter control circuit to perform constant-voltage control over a solar battery according to a certain initial voltage. SOLUTION: The voltage of the solar battery 1 charges a capacitor C1 and is supplied to an inverter main circuit 2. The AC output of the inverter main circuit 2 is supplied to a load L through an output filter 24 consisting of a reactor 22 and a capacitor 23. At this time, the inverter control circuit 3 performs control with the initial voltage which is lower than an open voltage. When the solar battery 1 is normally used, the initial voltage is set almost to the operation point of maximum output. Here, an initial voltage varying means 31a may be added which optionally varies and stores the initial voltage stored in a voltage comparator 31. Consequently, the device is easily adaptive to variation of characteristics of the solar battery 1.

Title: Write protecting system for memory
Inventor: KIMURA TOSHIHIRO
IPC: G06F21/60
Filed: 1987-07-23
Abstract: PURPOSE:To avoid such a case where the data stored in a memory is destroyed by the runaway of an MPU by inhibiting the writing actions in response to an address signal and a switch circuit which can be externally operated. CONSTITUTION:When an MPU writes the addresses 0-0FFF while a switch 13 kept turned off, the output of an AND 7 is set at L and the output of an AND 10 is also set at L. Thus the output signal passed through an inverter 9 is set at H with the output signal of an AND 6 kept at H. As a result, the inverse of CS terminal of a RAM 1 is kept at H even though the MPU gives accesses to the addresses 0-0FFF. Thus no data could be written into the RAM 1.
